    YouTube feed

    I'm trying to list the videos in a client's YouTube page. I got this code elsewhere in this forum:

    <xsl:variable name="youTubeFeed" select="umbraco.library:GetXmlDocumentByUrl('https://gdata.youtube.com/feeds/api/users/[userpage]/uploads', number($cacheRate))" />
    <xsl:template match="/">
      
          <xsl:for-each select="$youTubeFeed/*[local-name()='feed']/*[local-name()='entry']">
              <div style="margin-bottom: 10px;">
                  <h4><xsl:value-of select="*[local-name()='title']" disable-output-escaping="yes" /></h4>
                  <p>Result: <xsl:value-of select="*[local-name()='media:group']/*['media:description']" disable-output-escaping="yes" /></p>
              </div>
          </xsl:for-each>
      
      </xsl:template>

    This lists all the titles, but gives me no results for media:group/media:description. If I change that part to:

    <xsl:value-of select="*[local-name()='group']/*['description']" disable-output-escaping="yes" />

    ... it gives me the word 'Music' which is the content of the first node under media:group – media:category. What I actually want to get is the url attribute of media:group/media:player.

    Anyone know how to do this?

    Hi. Could you write here how the incoming feed xml fragment looks like?

    It looks like this (there is obviously more than one <<entry> node):

    The bits I'm actually interested in are media:group/media:player (the url attribute) and one of the media:group/media:thumbnail url attributes (although Idon't know how to pluck jus one from the 4 that are present).

    Thanks

    Well. You just need to write it as:

    ..bla-bla..   *[local-name()='group']/*[local-name() = 'description'] ..bla-bla..

    Thanks (I'd missed the second local-name()= !) – but do you know how I get the attribute of media:player?

    <media:player url='https://www.youtube.com/watch?v=uNIsz0gdcJA&amp;feature=youtube_gdata_player'/>

    The same way. For example:

    <xsl:variable name="url" select="*[local-name='group']/*[local-name() = 'player']/@url"/>

    local-name() just gets the name of an element without the namespace part.

    That works, thanks!

    Any idea how I'd get just the second of the media:thumbnail nodes?

    The second one can be selected with the XPath position() function:

    <xsl:variable name="thumbs" select="*[local-name()='group']/*[local-name()='thumbnail']"/>
    <xsl:variable name="thumb2" select="$thumbs[position() = 2]"/>
